Answer:
No, Sorry.
Step-by-step explanation:
Since the bases are different, you'll have to change them even if they have a exponent or not. If you dunno how to make the denominators the same, just multiply the two by eachother.
Example) 1/2 - 3/4
[tex] \frac{1}{2} - \frac{3}{4} [/tex]
Multiply 2 and 4 together, and then multiply the 4 to the one also. Multiply 2 to four and also to the 3.
[tex] \frac{4}{8} - \frac{6}{8} [/tex]
The subtract from there.
[tex] \frac{ - 2}{8} [/tex]
and then Reduce (if needed.)
[tex] \frac{ - 1}{4} [/tex]
